How do the hair of certain animals help in keeping their bodieswarm?NCERT Class VIIIScience - Exemplar ProblemsChapter 3. Fibre and Fabric



Let me explain:-
see, the hairs in between have air
so, we can say that the bodies of such hairy animals are covered with a layer of air.
This air covering is a great insulator of heat.
So, it does not allow the internal body heat(formed as a result of metabolic activities) to escape. Thus, the body is kept warm.
